Abstract

There is provided a technique for efficiently acquiring a tomogram of an eye portion. A diagnosis support apparatus includes a wide-area image acquisition means for acquiring a wide-area image of an eye portion, a detection means for detecting a lesion candidate on the eye portion by analyzing the wide-area image acquired by the wide-area image acquisition means, a determination means for determining a parameter associated with acquisition of a tomogram of the eye portion, based on a lesion candidate detection result obtained by the detection means, and a tomogram acquisition means for acquiring a tomogram of the eye portion based on the parameter determined by the determination means.

Claims

1. A fundus image acquiring apparatus comprising:

a fundus image acquisition unit adapted to acquire a fundus image of an eye portion;

a detection unit adapted to detect a location of an optic papilla of a fundus of the eye portion from the fundus image;

a tomogram acquisition unit adapted to acquire, based on the location, a tomogram of the fundus in an area located around the optic papilla by scanning a measurement light in a circle in the area located around the optic papilla; and

a display control unit adapted to cause a display unit to display the fundus image and the tomogram, to cause the display unit to display as a parameter a resolution of the scan, and to cause the display unit to display a display indicating a location corresponding to the acquired location of the tomogram on the fundus image which is displayed on the display unit.

2. An ophthalmic apparatus comprising:

a detection unit adapted to detect information regarding an optic papilla of a fundus of an eye portion from a fundus image of the eye portion;

a tomogram acquisition unit adapted to acquire, based on the information, a tomogram of the fundus in an area located around the optic papilla by scanning a measurement light; and

a display control unit adapted to cause a display unit to display the fundus image and the tomogram, to cause the display unit to display as a parameter a resolution of the scan, and to cause the display unit to display a display indicating a location corresponding to the acquired location of the tomogram on the fundus image which is displayed on the display unit.

3. The ophthalmic apparatus according to claim 2, wherein the tomogram acquisition unit acquires the tomogram by scanning a measurement light in a circle in the area located around the optic papilla.
